Computer Technologies essays

Computer Technologies essays At the end of the Cold War computer technology was on the verge of new era. Glocal satellite communications and the Internet opened a new portal to the world and if the U.S. Navy wanted to stay the dominant power to control the seas it had to take advantage of every technological advancement and innovative idea. Organizing a private intranet network incorporated with web applications and technology quickly became the backbone of global and local Navy vessell coordination and synchronization. High-tech multitask computers became the core of projects for new Navy ships where their use made the crew volume decrease by a hundred, a hundred and fifty percent. Also the versatility of cumputer and web applications allows the Department of Navy to stay just inside its budget, which is declining every year, by the integration of comercial everyday software into their systems to help the Navy build their global computer network. Applications like these, some of which people even use in their h omes, saves the Navy money by not having to purchase and design special software for military-only purpose. The most significant and impactful project for the network centralization of the Navy using modern computer technology is the "Information Technology for the 21st Century" project also called IT-21. Ever since its deployment the IT-21 quickly gave favorable results and promising future, and one of the most valuable benefits from it, was the coordination of vessels to conduct massive operations: : "This first IT-21 deployment was a revolution in connectivity for cruiser-destroyer (CruDes) units. The combination of enhanced IT systems, expanded connectivity paths, and power projection placed them in a prominent role during the execution of Tomahawk strikes in support of Operation Allied Force in May and April 1999. A group consisting of a guided-missile cruiser, guided-missile destroyer, destroyer, and two attack submarines conducted the initial p...

Free Essays on The Mentally Challenged

When one looks at the world around, what is it that one notices? The way people walk? The way people act? What about those that don't walk, talk, or even look like most people? Everyone, regardless of who that person may be, needs to be reminded of the saying, "You can't judge a book by its cover." A lack of understanding is what leads to prejudice. The prejudices are not only against people with different skin tones, ages, or sexes, these prejudices also extend to judgments made against the physically and mentally challenged. Through my experience at the centre for the mentally challenged, I have learnt further about and understood these people. The Mentally Challenged express themselves in a pure clear way; they may rock their bodies to and fro, flick fingers in front of their face, make odd noises or have difficulty relating themselves to space, making one feel uneasy but it’s not like they can help it. One must understand that they have poor motor and speech development; t hey are only trying to express themselves, just like us. The mentally challenged require one step directions, all instructions and steps should be broken down as understanding and following more than one thing at a time is very difficult. Everyone is capable of learning; it’s just that some people learn slower. I remember trying to explain the simple game of â€Å"Memory† to the mentally challenged; they could not understand how the game was played. In the end, the cards had to be flipped over and the game was changed into a game of just matching, the mentally challenged had to be constantly shown how to play until only some got it. The mentally challenged require demonstration in concrete form, have a short attention span and short-term memory. Though they have poor memory recall, I noticed that they can carry on repetitive routine tasks without being reminded, such as going for lunch and packing up after playing.

This can be an issue should the creditors demand repayment all at once.

An increase in this ratio could be looked at negatively by the managers and shareholders. One would need to look at the reason for the increase in debt from a year ago to see if it is justified. For instance was the increased debt due to long term financing for an expansion of the business or due to increased purchase of inventory that isn't selling?

Botfly Facts and Tips for Removal

Botfly Facts and Tips for Removal The botfly is a type of parasitic fly, best-known for disturbing images of its larval stage in skin and horror stories of infested people. The botfly is any fly from the family Oestridae. The flies are obligate internal mammalian parasites, which means they cant complete their life cycle unless the larvae have a suitable host. The only species of botfly that parasitizes humans is Dermatobia hominis. Like many species of botfly, Dermatobia grows within the skin. However, there are other species that grow within the hosts gut. Fast Facts: Botfly Common Name: Botfly or Bot FlyScientific Name: Family OestridaeAlso Known As: Warble flies, gadflies, heel fliesDistinguishing Features: Hairy fly with a metallic bot appearance. Infestation is characterized by an irritated bump, with a hole in the center for the larval breathing tube. Movement may sometimes be felt within the lump.Size: 12 to 19 mm (Dermatobia hominis)Diet: Larvae require mammalian flesh. Adults do not eat.Lifespan: 20 to 60 days after hatching (Dermatobia hominis)Habitat: The human bot fly lives primarily in Central and South America. Other botfly species are found worldwide.Conservation Status: Not evaluatedKingdom: AnimaliaPhylum: ArthropodaClass: InsectaOrder: DipteraFamily: OestroidaeFun Fact: Botfly larvae are edible and are said to taste like milk. How to Recognize a Botfly With its hairy, striped body, you could say a botfly looks like a cross between a bumblebee and a house fly. Othersv liken a botfly to a living bot or miniature flying robot, because the reflective hairs give the fly a metallic appearance. The human botfly, Dermatobia, has yellow and black bands, but other species have different coloration. The human botfly is about 12-19 mm in length, with hair and spines on its body. The adult lacks biting mouthparts and does not feed. In some species, botfly eggs are easily identified. For example, equine botflies lay eggs that resemble tiny drops of yellow paint on the horses coat. The fly is best known for its larval stage or maggot. Larvae that infest skin grow under the surface, but leave a small opening through which the maggot breathes. The larvae irritate skin, producing a swelling or warble. Dermatobia larvae have spines, which worsen the irritation. Bot fly larvae cause a lump with an open center, through which the breathing tube may be visible. Petruss Where Do Botflies Live? The human botfly lives in Mexico, Central America, and South America. People who live in other areas generally get infected while traveling. Other species of botfly are found across the globe, primarily (but not exclusively) in warm tropical and subtropical regions. These species infest pets, livestock, and wild animals. The Botfly Life Cycle Cuterebra sp. botfly larva extracted from the neck of a dead rabbit. Katja Schulz The bot fly life cycle always involves a mammalian host. Adult flies mate and then the female deposits up to 300 eggs. She may lay eggs directly on the host, but some animals are wary of botflies, so the flies have evolved to use intermediate vectors, including mosquitoes, houseflies, and ticks. If an intermediate is used, the female grasps it, rotates it, and attaches her eggs (under the wings, for flies and mosquitoes). When the botfly or its vector lands on a warm-blooded host, the increased temperature stimulates the eggs to drop onto the skin and burrow into it. The eggs hatch into larvae, which extend a breathing tube up through the skin to exchange oxygen and carbon dioxide. The larvae (instars) grow and molt, finally dropping from the host into the soil to form pupae and molt into adult flies. Some species do not develop in skin, but are ingested and burrow into the hosts intestine. This happens in animals that lick themselves or rub their nose on body parts. After several months to a year, the larvae pass through the feces to complete its maturation process. In most cases, bot flies do not kill their host. However, sometimes the irritation caused by the larvae leads to skin ulceration, which can result in infection and death. How to Remove Botfly Larvae Botfly larvae Hypoderma diana under a deers skin. Avalon_Studio / Getty Images Infestation with larval flies is termed myiasis. While its a characteristic of the botfly life cycle, it actually occurs with other types of flies, too. There are several methods used to remove fly larvae. The preferred method is to apply a topical anesthetic, slightly enlarge the opening for the mouthparts, and use forceps to remove the larvae. Other methods include: Using a venom extractor syringe from a first aid kit to suck the larvae from the skin.Oral dosing with the antiparasitic avermectin, which leads to spontaneous emergence of the larvae.Flooding the opening with iodine, which causes the fly to poke out of the hole, facilitating its removal.Applying the sap of the matatorsalo tree (found in Costa Rica), which kills the larvae, but does not remove it.Sealing the breathing hole with petroleum jelly, white glue mixed with insecticide, or nail polish, which suffocates the larvae. The hole is enlarged and the carcass is removed with forceps or tweezers.Applying adhesive tape to the breathing hole, which sticks to the mouthparts and pulls out the larvae when the tape is removed.Forcefully squeezing the warble from the base to push the larvae through the opening. Killing the larvae before removal, squeezing them out, or pulling them out with tape is not recommended because rupturing the larvae body can cause anaphylactic shock, make removal of the entire body more difficult, and increase chance of infection. How to Avoid a Botfly Infestation The easiest way to avoid getting infested with botflies is to avoid where they live. Since that isnt always practical, the next best tactic is to apply insect repellent to deter flies, as well as mosquitoes, wasps, and ticks that can carry fly eggs. Wearing a hat and clothing with long sleeves and pants helps to minimize exposed skin. Sources Felt, E.P. (1918). Caribou Warble Grubs Edible.

Why Detaining terrorist in Guantanamo Bay was against American Essay

Why Detaining terrorist in Guantanamo Bay was against American Philosophy - Essay Example Hamdan, a diminutive Yemeni who had been detained in Guantanamo Bay for more than five years, was kept in a tiny room kept cold with air conditioning, while he had nothing proper to cover himself, not even a pair of socks. Swift shared his thoughts with his partner law professor, Neal Katyal, who had been preparing legal briefs on the matter of President Bushs military tribunals. Katyal made his own efforts in writing drafts for the Supreme Court and the Court of Appeals trying to figure out what the Department of Defense was going to include in the new guidelines for the Guantanamo Bay detainees. Although the Supreme Court declared the military tribunals as illegal, still Congress protested and passed its own ruling regarding the secluded Guantanamo. This was a defeat of American philosophy. So, the lawyers, Swift and Katyal, decided to challenge Congress. Why detaining terrorists in Guantanamo Bay is against the American philosophy has many fair reasons. It is not legal in any case, according to human rights, to deprive a prisoner of war of his legal right of either being tried or released if proved innocent. The detainees at Guantanamo Bay are neither tried nor released, and they do not even know why they have been brought there and kept in brutal torture. Detainees have been held in Guantanamo Bay without charge for more than five years many of whom have been subjected to severe abuses. This has significantly torn apart American reputation of war. Guantanamo has become an epitome of lawlessness in the eyes of the whole world. American philosophy has enabled the United States to stand among one of the strongest democracies which support human rights and which make other nations comply with the international standards of human rights and humanitarian laws. But now, even the allies of the Bush’s administration are looking at Gu antanamo policy as a failure and violation of American philosophy of war and human rights. Carafano and Rona state that: That the

Dilemma Analysis #2 - Coursework Example The ethical issue to be addressed, therefore, is non-maleficence and beneficence. Jared decides that to make things right, he and the company must start clean-up exercise in the river and notify the authorities. This, from his perspective, will help in making the company better positioned to move ahead with a clear conscious and also be part of the corporate social responsibility. The decision is also based on the fact that reports have shown that the chemical has negative effects on the people’s health, although in large amounts, and also on the fish which the people consume. However, the dilemma comes in when the authority has been unaware for a long time and the fact that clean up exercise may not be successful since other factories continue to dispose of their chemicals into the same river. The exercise is also repulsively expensive for the company. In addition, notifying authorities will attract hefty fines to the company since it is a foreign entity. Doing the right thing does not have to involve the authority or expose the company to fines and unnecessary expenses. On realizing the existing problems, the management can decide to start engaging on doing the right thing from that point onwards. This implies that the company should adopt the right processes for chemical disposal and engage more on social responsibility to enhance their reputation. Utilitarianism is a moral philosophy which is based on analyzing the consequences. This means that first, the managers have to analyze the situation, the existing problems and seek for the alternative actions regarding the situation. In this case, we compare working to do what is right from that day on with exercising the clean-up. The second step involves estimating the costs of the actions and the benefits and later selecting the best alternative. Clean-up and reporting are costly and dangerous to the reputation of
